(1) If you quit work due to a change in working conditions that meets the requirements of RCW 50.20.050 (2)(b)(v) through (x), the department will not deny benefits solely on the basis that you continued working for a brief period of time following the change. However, you must demonstrate to the department that the change in working conditions was the motivating factor for quitting work.

(2) "Brief period of time" means the amount of time a reasonably prudent person would have continued working after the change in circumstances.
